Recent Flux & Frequency History
4U 1626-67 has a period near the the Nyquist limit of 2.048s for the DISCLA data used by the Monitor, so that these measurements
lose some power due to aliasing. The flux has been corrected by a factor of
1.03 to obtain the values plotted above. Data have been averaged over 2 days.Monitor ParametersASCII FileTypical Pulse ProfilePS File
